Belt drive compressor

Ok guys. Most know the 80's square style AC compressor can be made into a Air Compressor, but has anyone stuck one on a jk? I have a unit coming to me to try but always look the brotherhood for input....

I believe it's off road only that sells the mounting bracket with belt and pulley for a york compressor. If that's what your talking about when you say square compressor.

Kilby Enterprise makes the mounting kit for JK's. ORO (and others) resell it.

I know. I am just hoping i can get a clutch for a serpentine belt that will fit AND find room for it.

I know i could have bought a compressor by now, but it is more fun to try and make one

I have the ORO system. It's awesome.

I can fill tires and use air tools in the middle of nowhere.

Eta: I do believe that something was done to the York so that it could compress air and not Coolant.

Is kilby still in business?

I have the kilby setup, with a junkyard compressor. I only ordered the parts I had to from there, and sourced the rest at Home Depot and Ryder Fleet Products (Serpentine).

I have had a Kilby setup on 2 jeeps now, and it works well. If I had to do it again, I would probably do the dual ARB electric setup now so as not to add parts to the engine bay. Up until that came out, the York really was the best as far as CFMs. The new ARB comes close now though.

thats what snice about the york is you dont need to do anything to it to make it pump air. i ran one on my bagged suburban that filled 35gal tank (well 2 tanks that equaled 35gal). i have a spare that i kept when i sold it and id love to get it on the jeep but that damn bracket kit is expensive

Well, I'm not an "expert," but my understanding is the only thing you need to do is put an oil separator on the output of the compressor and periodically refill the compressor with oil. There is actually a mod that feeds the drain from the separator back into the compressor, though I believe it requires manual intervention to do so?

My father in law is a pure redneck and has done the needed change to the compressor. There is a port that. Needs to be pluged and put oil in the compressor. I have assisted but not done it on my own.

My setup. The only thing I bought was the ORO's bracket and pulley. If I had the brackets in front of me, I could've replicated it. Brackets for the check valve and separator I made. Used an aluminum air block for the pressure switch, pop off valve, gauge, and chuck. Did it all for under $500. Picked up a new 6 groove serpentine clutch from Ryder fleet services, $120 shipped. 165 PSI shut off, 150 PSI turn on Viair pressure switch. 175 PSI pop off valve, check valve, and separator from Grainger. I could do away with the check valve and separator. Don't need it IMO. Could be done for under $400. Used 4,000 PSI hydraulic hose for the discharge on the compressor. It makes A LOT of heat and pressure and regular air hose bubbles and could burst. The steel braided hydraulic hose works MINT. I actually removed the head on the compressor, drilled and tapped for normal NPT thread and put a barb at the end. Fuck giving Kilby $65 a fitting for the head...stupid.









Since those pics all the red hose has been upgraded to black Goodyear airline (red was Lowe's air line hose, sucks BALLS. It expands too much and cuts itself on the clamps).

OROs unit comes with a belt. IMO, you need nothing from ORO. The new pulley they supply you is 3.5" outside diameter. I had a buddy of mine machine one out of billet aluminum since the Chinese junk they supplied failed. Pressed in a German sealed bearing and that's it. The belt is a Gates off the shelf belt. I'll get the part # from my spare belt in the truck and let you know...

I had a complete Kilby OBA system on my YJ, a great kit. I even ran the front ARB off of it using Kilby's pressure step-down valve, manifold, etc. Had chucks piped in front & back, a 1.75 gal tank underneath the rig and we plumbed it with plastic 18 wheeler air brake line using quick connects. Only issue I had with it was the switch Brad supplied, which was prone to dirt contaminating the contacts. I got a sealed Viair switch with the same switching pressure limits from Rubicon Express, cured the matter completely. On my JK I opted for a Powerplant so I had a two for one solution. Air pump works great for tires but the Kilby system would kick it's ass in a comparison.

The main difference between the York(used in ORO and Kilby kits) and the common AC compressors is that the York has an oil pan, while the AC compressors are lubricated by the refrigerant.
I've seen many guys convert AC compressors to air only by simply installing an air tool oiler on the intake line and filling it periodically. Works great.

I have a compressor sitting in my garage waiting for me to do this as well. My electric doesn't work anymore so I will probably get on this during the summer after I get back to the U.S.
